Durham finish with a flourish
A stand of 116 in 18 overs between Paul Collingwood and Keaton Jennings carried Durham to a five-wicket home win against Surrey in their final Royal London Cup group game.
Rain cut short the visitors' innings on 189 for six after 44.5 overs and after a break of more than two hours Durham were required to score 198 in 37 overs.
The hosts had reached 11 for two after three overs when a short break saw the target revised to 190 in 33 and they surpassed the total with nine balls to spare.
They had slipped to 69 for four when Collingwood emerged to complete an outstanding all-round performance. He took two for 25 in 10 overs then thumped an unbeaten 62 off 56 balls.
Jennings survived sharp return chances to George Edwards on 31 and Azhar Mahmood on 40 but belied his reputation as a stodgy four-day opener by making 70 off 67 balls before skying a catch to fine-leg off Jack Winslade with five runs needed.
Durham now have to wait until the other teams have played their final games next Wednesday to discover whether they have qualified for the quarter-finals.
Surrey, with no chance of progress, had left out all their senior bowlers apart from Azhar.
Among the youngsters Surrey drafted in was 19-year-old seamer Winslade, who conceded 61 runs in 6.3 overs.
The target was 48 off six when Durham took the batting powerplay and Surrey had to recall Winslade. Jennings drove his second ball back over his head to reach 50 off 52 balls.
Surrey made a brisk start as Steven Davies and Tillakaratne Dilshan took 35 off the first six overs before John Hastings bowled the Sri Lankan with his third ball.
Collingwood also struck with his third ball when Vikram Solanki drove a low catch to cover after labouring for 37 balls to make 14.
Davies looked a high-class player in reaching 50 off 54 balls, but that was in the 25th over, which meant he had faced little more than a third of the strike. He fell for 56 when he lofted Jennings' fifth ball to mid-off.
At 108 for five Azhar found an impressive ally in 21-year-old Aneesh Kapil as they shared a stand of 69 in 13.5 overs.
Steep bounce from Paul Coughlin accounted for Azhar for 34 but Kapil was still there on 43, made off 53 balls, when the rain arrived.
